Do not believe in anything (simply)because you have heard it.Do not believe in traditions because theyhave been handed down for many generations.Do not believe in anything because it isspoken and rumoured by many.Do not believe in anything (simply)becauseit is found in your religious books.Do not believe in anything merelely on the authorityof your teachers & elders.But after observations & analysis,when you find anything that agrees with reasonand is conducive to the good & benefit of one & allthen accept it & live upto it . Buddha ( Angutra Nikaya , vol 1, 188-193 )
